IntroductionCloud computing is "a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources that can be rapidly provisioned and released with little management effort minimal or minimal interaction with the service provider" ' (Grance, 2009). Therefore Cloud Computing is strictly considered a computing model, not a technology. The origin of the term cloud computing is unclear, but according to the study (Lakhmi Chand Goyal, 2013), it seems to evolve from the practice of using the cloud to visualize the network and communication system. The word cloud is just a metaphor for the Internet, based on the typical use of cloud-shaping computing with a set of special algorithms on distributed devices and infrastructures. Recently, especially in the late 20s, with the development of information technology and economy, the development of cloud computing has been supported by public organizations and most private scientific companies. Now the long-standing dream of computing, computing as a utility, has the potential to be realized and transformed in much of the IT industry because the advancing cloud computing model will make software services more attractive and improve design methods and purchase. the computer hardware. MethodWhile the last report roughly introduced and discussed the current situation of information technology, in the second report it was decided to introduce one of the latest developments in the field of information technology. Computing, a recently invented model of computers, has attracted public attention. So it will be worth doing research on this topic. The information was all collected from secondary documents and sources on the website or in the library between April 15th and 20th. At the beginning,... in the middle of the paper... he is precisely capable of creating this type of circumstance. In the future, more success will be achieved by using cloud computing in other business fields. Conclusion As a new field that has developed in less than 20 years, cloud computing still has a long way to go. But the current effect of the use of cloud computing on various areas has shown that this model will bring a revolution in the way of using web services and the online browsing experience. And commercial settings, such as banks, will also adopt a more powerful and convenient method to serve the public. Ultimately, the entire society will benefit from this scientific change. Of course, one important thing that cannot be ignored is that to achieve the above-mentioned goals you first need to solve the three problems, latency reliability and security. And the three problems will constitute the crucial directions of cloud computing.
